Searchin for signal on satellite in 2...

This happened when the first 5 new HD came out a few weeks back. RBR fixed it. When the new HD channels just lit up the other day, I get the searchin for signal 771 but only on some of the new channels and other new ones work fine. Any help much appreciated. Thanks

In the past some have reported issues with tuner #2 on HR20s. If you are using a two coax system try switching the wires and see if the problem follows the wire or stays with the tuner. I had the same issue a while back. Tuner finally died completely. All I got was a black screen and 0s on all the meters. Had to replace it.

I had the exact same thing happen to one of my HD DVR's on Wednesday. Got a searching for signal error on tuner 1 but only on certain channels, others came in fine. A look at the signal strength meter showed 95% for tuner 2, 0% for tuner 1, even when receiving a picture on tuner 1. I also noticed the cooking channel showed up as "not subscribed" while flipping around the channels to see what was coming in and what wasn't. A RBR fixed everything.

So, I did RBR and channels came in but then went back out in a few minutes,again searchin for 771. I gotta feelin my HR20 is dyin after 3yrs.
Gonna switch coax maybe get lucky and its the wire. Cant be alignment issue or could it? Tried refesh thru website but nothin happened no reset. Help, TY

I tried troubleshootin RBR, disconnect and reconnect wires, swapped tuners,etc. Then, last nite, i recorded program and suddenly the other tuner was pickin up all channels that I wasnt gettin and all signals strengths were excellent and system test was perfect. Today, came home, the same searchin for signal problem came back again on only some HD channels. When I did system test, it stated possible alignment problem or distribution problem with cabling. Any suggestions much appreciated.
